Reach so as to tamper with? (3,2)
I believe the answer is:
get at
This clue might be a double definition.
'reach so as' is the first definition.
'get at' can be an answer for 'reach' (getting at is a kind of reaching). I am unsure of the 'so as' bit.
'tamper with?' is the second definition.
(thesaurus)
'to' is the link.
Can you help me to learn more?
(Other definitions for get at that I've seen before include "Unfairly influence" , "Nobble; gain access to" , "Pick on - gain access to" , "Intend" , "Criticise (someone)" .)
